I'm making a set of FFXV character Sims and I've got nothing close to suitable for Gladio's hairdo , basically. Medium length, shaved/undercut on both sides, messy?

I tried searching various keywords on SimsHairs and TSR to no avail, so it's time to crowdsource some ideas.

(Bonus: His exact tattoo is a lost cause unless I make it myself, but tattoos- Ambitions or accessory- of feathers or birds of prey would be useful.)

There are several shaved side hairs on Ifcasims retextures, but I don't know if any of them have the length you are looking for.
Take a look through here and maybe you will find one that suits your needs.

The only mullet-like hairstyle I can think of is this one of Peggy's: http://simshairs.com/id-801-lion-st...s-by-peggyzone/
